A porn parody of "Game of Thrones" has gone viral, and it's even more adult than the original. Like its mainstream HBO counterpart, "Storm of Kings XXX" is an action-packed (and we mean that in more ways than one) series about a quest to rule the throne.

The four-part series by Brazzers, a leading porn production company, has amassed an impressive 1.5 million views to date. It also earned a very serious write-up in Vanity Fair.

"Storm of Kings XXX" isn't the first adult film to mimic the Emmy-winning fantasy drama. But what "Game of Bones" and "Gay of Thrones" lacked, Brazzers delivers: an unwavering commitment to authenticity. The company cast performs that actually look like their characters, invested heavily in CGI, and wrote a script based on years of genuine fandom.

Tech Insider spoke with Andy Paterson, a producer with Brazzers, on how the series came together. Here's a safe-for-work look inside "Storm of Kings XXX."

"Storm of Kings XXX" takes all your favorite parts about "Game of Thrones," jumbles them together, and adds more sex.

"Storm of Kings XXX" follows evil King Jasper in his quest to protect the throne, and those who try to undo him. The cast is packed with familiar faces, including a Jon Snow-like character named John Doe and a new Mother of Dragons, Daniellys Tarus.

Of course, it wouldn't be "Game of Thrones" without some bloodshed.

In the first episode, John Doe decapitates a member of the King's Guard. King Jasper slays the entire family of a Sansa-inspired character right in front of her, reminiscent of the show's devastating "Red Wedding" episode.

"Reviews online, especially from Brazzers fans, have been loving the plot," Paterson says. "It revolves around the key elements: deception, decapitations, and dragons."

The cast looks pretty familiar.

Performers were chosen based on three main factors. (Accent was not one of them. Vanity Fair reports that the Daenerys character has a quintessential SoCal accent.)

"One of the first considerations is their potential to resemble [their mainstream counterpart] through costuming, makeup, and acting ability," Paterson says.

While the blonde, blue-eyed King Jasper makes for a decent grown-up Joffrey, we admit this Khal Drogo knock-off could use some work. At least he has the eye shadow down.

Paterson explains that the performer's ability to take on the character's essence and to perform sex on camera is also taken into consideration.

The project's budget reached into six figures.

The production budget for "Storm of Kings XXX" doesn't come close to that of "Game of Thrones," which costs about $6 million per episode. But it's impressive for an adult film.

Brazzers product director Mario Nardstein told Vanity Fair the project was given a "flexible budget," and that high-profile productions range from $100,000 to $1 million to make. By comparison, a typical Brazzer shoot costs between $10,000 and $20,000.

Where did that money go? Paterson says the company invested a lot of time (and thus, money) into animating the series' dragons and featured them prominently.

Like "Game of Thrones," "Storm of Kings XXX" is no laughing matter.

Brazzers' goal with a porn parody is to immerse the viewer in the world as much as possible — without making it cheesy. Awkward dialogue leads people to giggle, which distracts them from the real reason they're watching the adult film.

"By making a parody that isn't laughable or humorous like previous productions have done, we're able to place the viewer more directly into the scene," Paterson says.

Winter is still coming — sort of.

John Doe encounters a "Wild One" draped in furs and little else in the forest, and the pair launches into combat. But they must quickly put their differences aside when a withering, old blue man called a Dead Walker approaches.

The crew must juggle imitation of the original series with infringement.

"We follow a strict compliance and legal review pipeline before scenes are released," Paterson says. "They give us their notes, and we adjust the scenes."

The crew used the series as an opportunity to fulfill their greatest wishes as fans.

Spoiler alert: The Daenerys character ends up on the Iron Throne, because it's an itch the crew was dying to scratch. She also copulates with John Doe.

"I feel like every season of 'Game of Thrones,' we want that character (Daenerys) to take an army to Westeros but it never happens," Paterson says. "I wanted to see it, and Brazzers made it happen."

Writer and director Dick Bush (that's his real name) also made sure to give King Jasper a gruesome send-off — death by dragon — to feel better as a fan.
